Fry and serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Finely mashed potato
- Forms the bulk of the croquette and gives a soft, tender interior.
- Butter
- Adds fat and richness, contributing moisture and a smooth mouthfeel.
- Sweet milk or cream
- Moistens the potato so the mixture holds together and shapes easily.
- Egg
- Binds the mixture and, as a coating, helps the cracker crumbs adhere.
- Cracker crumbs
- Forms a crisp, browned outer crust during frying.
The step that matters
Fry in hot lard until golden brown. If the lard is not hot enough, the croquettes absorb excess fat and turn greasy, while the crumb coating may not brown and crisp properly. Adequate heat sets the crust quickly, keeping the interior moist.
Swap the potato
How well each one fits the dish's main ingredients (pepper, butter, milk, egg):
- Capsicumfits about as well
- Potatothe original
- Asparagusfits about as well
- Chivefits less well
Fit is the average pairing score against pepper, butter, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
